Title: Method to synthesize graphene-based amphiphilic janus nanosheets

Abstract

A facile and scalable method to prepare graphene-based amphiphilic Janus nanosheets with high efficiency utilizing the formation of hydrogen bonding to immobilize graphene oxide (GO) on the surfaces of starch microspheres. After selective functionalization of the exposed surface using alkylamine, amphiphilic Janus nanosheets (AJN) were obtained by releasing the nanosheets from the starch microspheres.
